A technique for producing wheat haploids through ultra-wide crosses followed by embryo rescue was improved by successfully selecting pollen donors from different subfamilial species and applying a plant growth regulator. Efficient crossing procedures were developed by using stored pollen and detached-tiller culture. Production of wheat haploids from diverse genotypes is efficient enough to obtain two haploids per wheat spike. This technique could be useful as a strategy for reducing the time required to obtain homozygous breeding lines and improving selection efficiency of wheat breeding programs. Procedures for doubled haploid production are described.
